Expert Answer
Let f(x) = begin mathsize 14px style square root of sin space x space plus space 3 x squared end root space end style
begin mathsize 14px style fraction numerator d f over denominator d x end fraction space equals space fraction numerator 1 over denominator 2 square root of sin space x space plus space 3 space x squared end root end fraction cross times open parentheses cos space x plus space 6 x space close parentheses space equals space fraction numerator open parentheses cos space x plus space 6 x space close parentheses over denominator 2 square root of sin space x space plus space 3 space x squared end root end fraction end style

Let  g(x) = x2
 
dg/dx = 2 x

 
begin mathsize 14px style fraction numerator d f over denominator d g end fraction space equals space fraction numerator d f divided by d x over denominator d g divided by d x end fraction space equals space fraction numerator stretchy left parenthesis space cos space x space plus space 6 space x stretchy right parenthesis over denominator 2 space square root of sin space x space plus space 3 space x squared end root space cross times space 2 x end fraction space equals space fraction numerator stretchy left parenthesis space cos space x space plus space 6 space x stretchy right parenthesis over denominator 4 x square root of sin space x space plus space 3 space x squared end root end fraction end style
